      KtMutableSet<T> 
      get
      kt
      
    
    
Wraps this Set with a KtMutableSet interface.
In most cases you don't want mutability. Use toImmutableSet instead.
Mutations on the KtMutableSet are operated on the original Set.
Implementation
KtMutableSet<T> get kt => DartMutableSet.noCopy(this);
